What is son?

Synovium or synovial membrane is a soft tissue that lines the surfaces of synovial joints or joints with cavities. Some joints that have a synovium are wrist, elbow, shoulder, hip and knee. The word synovium is derived from Latin for "eggs" because the synovial fluid inside the joint has consistency and appearance of egg white. The tendons in the hand and leg have a similar structure to the synovial membrane, called the synovial case.

Although there is a variation between different types of nephew, tissue usually has two layers, Intima and Subintima. Subintima is an outer layer that can consist of different types of connective tissues, from oily to fibrous to alveolar. Intima or inner layer consists of an extremely thin leaf of cells. The synovial membrane is used to content and protect the synovial fluid of suspension and lubrication, which is essential for the proper functioning of the joints.

There are two types of cells present in the intima of son, fibroblasts and macrophages. Synovial fibroblasts prodThey catch two important substances for synovial fluid, hyaluronan and Lubcin. Hyaluronan is a long-chain sugar polymer, which gives the synovial fluid its consistency-like egg-white and helps to keep it on the spot inside the joint. Mazin keeps the joint lubricated to promote movement and prevent injury. Macrophages are a type of white blood cells that absorb and destroy unwanted particles in the synovial fluid.

Depending on the joint in question, the surface of the intima may be smooth or covered with villi, small hair similar to hair that allows son to change the shape when moving the joint. Under the intima is a dense network of capillaries or small blood vessels that maintain synovial membrane and cartilage inside the joint supplied by nutrients.

In -rescue states, including rheumatoid arthritis, synovium can thicken and irritate, causing joint and damage disorder. Irritated synovial membrane can produce an attachmentIsh many synovial fluid, which makes it difficult to achieve cartilage for nutrients, or can absorb too many nutrients themselves, similarly leads to sub -renewal of other parts of the joint. Finally, the damaged synovial membrane can produce enzymes that destroy cartilage.
